Arles' weapons this time are the "Monstaa" who became cards. Call Monstaa from the cards you get and win the card battle with the enemies who are blocking your way! If you set the jewel that you can get in the adventure on the card (jewel tuning system), Monsta will power up and evolve. Monstaa can only get the cards that the enemy has when he beats the enemy. Monsuta that you have seen or made friends with are recorded in Arles's "Monsuta Ajiten", so collect and tune all the Monsutas to make your own "Monsuta". Let's make "Monsta Ajiten"!
